SO sad....I looked on FB & 14 mutual friends...What is also harsh is the person in the surveillance video who is called the suspect (I think it was ABC News had shared the video; it's online) is a young woman who looks like she could be a student or an actor or even corporate....she looks tall & big boned & is strolling along languidly, but with a few backward/sideward glances...meanwhile poor Mrs. Dustern was under 5 feet tall. I cannot imagine what could have possessed whatever culprit did this.
